A bright, nutty topping and creamy arugula pesto amp up the flavor in this roasted cauliflower steak recipe. It's a simple, satisfying, and delicious meal!
Jack and I made this cauliflower steak recipe for Valentine’s Day last week. We loved it so much that I knew I had to share it with all of you!
As a cook, one of my favorite things to do is to turn a vegetable into a main dish. This cauliflower steak recipe is a fantastic way to do just that. I start by searing thick slices of cauliflower in a hot cast-iron skillet until they’re deeply golden brown. Then, I transfer them to the oven and roast until they’re nutty and tender. To make them a meal, I serve them over a swoosh of arugula pesto and top them off with a quick garnish of herbs, capers, golden raisins, and nuts.
All together, the combination is simple, elevated, and absolutely delicious. The topping and the sauce contrast beautifully, and the meaty cauliflower steak is so satisfying. If you’re looking to shake up your regular dinner rotation, look no further. This cauliflower steak recipe is just the thing for you.
Cauliflower Steak Recipe Ingredients
Here’s what you’ll need to make this cauliflower steak recipe:
- Cauliflower, of course! In order to slice 4 cohesive steaks, I recommend starting with two heads of cauliflower. You’ll definitely have extra cauliflower florets leftover. Roast them alongside the steaks, or try one of the cauliflower recipes at the bottom of this post!
- Extra-virgin olive oil – You’ll use some for cooking the cauliflower and more for the pesto and the topping.
- Arugula pesto – This bright, peppery sauce is quick and easy to make in the blender. It uses basic ingredients like arugula, cashews, olive oil, and lemon juice.
- Pine nuts and hazelnuts – They add nutty flavor and plenty of crunch to the simple topping.
- Parsley – For fresh flavor.
- Golden raisins – Their sweet flavor balances the bite of the arugula pesto, and their chewy texture contrasts nicely with the crunchy nuts.
- Capers – For salty, briny flavor.
- Sliced red chiles or red pepper flakes – For heat.
- Lemon zest – It brightens the whole dish up.
- And salt and pepper – To make all the flavors pop!

How to Make Roasted Cauliflower Steaks
When you make this cauliflower steak recipe, the first step is cutting the cauliflower. Remove the outer leaves from the first head of cauliflower. Stand the cauliflower upright on its bottom stem, and cut the cauliflower in half from top to bottom. Then, slice a 1 1/2-inch-thick steak from each half of the cauliflower, keeping the core intact. Repeat with the second head of cauliflower. You’ll just use the cauliflower steaks in this recipe. Save the remaining florets for another use!
Next, sear the cauliflower steaks. Coat the bottom of a skillet with oil and place it over medium heat. Sear each cauliflower steak until it’s golden brown on both sides, work in batches as necessary.
Then, bake. Place the seared cauliflower steaks on a parchment-lined baking sheet, and season them with salt, pepper, and a bit more olive oil. Roast at 425°F until the cores are fork-tender, about 25 minutes.
Meanwhile, prepare the topping and sauce. Whizz together the arugula pesto, and mix together the topping ingredients.
When the cauliflower steaks are ready, plate them over the sauce and sprinkle them with the herb and nut topping. Add a final drizzle of olive oil, if you like. Then, dig in!
Cauliflower Steak Serving Suggestions
Served with the topping and sauce, these roasted cauliflower steaks are a light, yet satisfying meal on their own. If you’re in the mood for something heartier, add a bed of cooked grains under the cauliflower steak. Wheat berries, farro, quinoa, or couscous would all work well here. A few roasted chickpeas would be a nice garnish too!
Round out the meal with crusty bread or focaccia for sopping up the flavorful sauce. Enjoy!

Roasted Cauliflower Steaks
Ingredients
- 2 large cauliflowers
- Extra-virgin olive oil, for drizzling
- Sea salt and freshly ground black pepper
- Arugula Pesto
Topping
- ¼ cup pine nuts
- ¼ cup hazelnuts, chopped
- ¼ cup chopped fresh parsley
- ¼ cup golden raisins
- 1 teaspoon lemon zest
- 2 teaspoons capers
- 1 small fresno chili, chopped or ¼ teaspoon red pepper flakes
- 2 teaspoons extra-virgin olive oil
Instructions
- Preheat the oven to 425°F and line a baking sheet with parchment paper.
- Remove the coarse outer leaves of each cauliflower, then slice 2 (1½ -inch-thick) “steaks” from the center of each cauliflower, keeping the core intact. Cutting the steaks from the center is the best way to get slabs that will stay intact through the cooking process. You’ll have quite a bit of cauliflower leftover. Save it to make our Cauliflower Pasta or any of these cauliflower recipes another day!
- Heat a skillet over medium heat and brush with oil. Place one or two cauliflower steaks in the pan and sear for 2 to 3 minutes per side, or until golden brown. Repeat with the remaining cauliflower steaks. Transfer each steak to the baking sheet, sprinkle both sides with salt and pepper, drizzle with a little bit more olive oil, and roast in the oven for 22 to 28 minutes, or until the core is fork-tender.
- Make the topping: In a small bowl, stir together the pine nuts, hazelnuts, parsley, raisins, lemon zest, capers, chili, and olive oil.
- Assemble plates with a slather of the pesto, a cauliflower steak, spoonfuls of the topping, and another drizzle of olive oil, if desired, and serve.

The combination of arugula pesto, herbs, capers, golden raisins, and nuts adds an exquisite layer of flavors and textures to the dish, creating a perfect balance of sweet, salty, and tangy notes.

Serving this delicious cauliflower steak with crusty bread or focaccia to soak up the flavorful sauce sounds absolutely divine. I’m excited to try this recipe and enjoy a unique, elevated, and satisfying plant-based meal that’s perfect for a special occasion or simply to spice up the dinner routine.
Thank you for your comment! I hope you love the dish.
These were great!! I didn’t have hazelnuts so I used cashews and I roasted all the nuts. Awesome!!!
So glad you loved the recipe!
OMG! This has to be one of the most delicious meals I’ve ever eaten. I did make a couple of modifications. I used pine nuts and pecans, cran raisins and added a little pesto to the topping. I put it all on a schmeer of my homemade hummus. I also roasted a handful of cherry tomatoes alongside the cauliflower steak.
Hi Joan, I’m so glad you enjoyed it!
Any substitute for the arugula pesto? This looks so yummy!
Hi Kathy, these steaks would be great over romesco sauce!
We just made this for dinner and it was very good. Thank you for creating vegetarian recipes that are so flavorful.
Best cauliflower steaks ever! My husband can not do chili’s but it made no difference… wildly satisfying! We had roasted tomato/red pepper soup to add some base colours. (he’s thanked me 3 times for a delicious dinner) … happy veggies say thank you for all the love and the lemons!
I’m so glad you loved the recipe!
Where is the recipe for the arugula pesto?
Hi Sandra, it’s linked in the recipe: https://www.loveandlemons.com/arugula-pesto/
Wow–this was delicious! There are so many textures and layers of flavor in this one. While I loved it as the main dish, my husband would agree with another poster and have me serve this as a side dish–he loved it though! Since my family doesn’t do well with chili spice, I substituted some chopped pimentos.
I’m so glad you enjoyed it!
We made this last night and it was delicious! The lemon zest in the topping provided the perfect amount of ‘zing’. However, I didn’t find this filling on it’s own, it definitely needs a side or another course.
This dish has left me drooling. I absolutely love cauliflower done this way. It’s my second favourite way to use cauliflower after cauliflower wings.
The images look amazing as always.
Thanks for the recipe I will definitely be giving this a try.

I’m not going to make this exactly but I’m going to use your stovetop > oven technique to make cauliflower nachos! Normally I just roast the slabs and then broil them with nacho toppings but it’s a struggle to get color on them. Great idea, thanks!
